I applaud this effort, but you need to distribute the source code
(whether modified or not) for the Cygwin DLLs, and possibly other
packages like OpenVPN and VPNC itself. Cygwin is GPL'd, so if you
distribute the binaries, you have to distribute the source, too .
I don't see any real reason to use a modified Cygwin DLL. The Cygwin
folks take great pains to ensure backwards compatibility, so you could
instruct users to install Cygwin from www.cygwin.com and add the Cygwin
bin directory to their path . That would obviate the requirement for
 Note: Do NOT instruct users to copy the cygwin1.dll to the VPNC
Front End directory.
